| titleOfInvention | Bonded articles and process for producing the same |
| abstract | A process for producing a bonded article of ceramic bodies comprising steps of: machining the ceramic bodies to be bonded to form machined surfaces with average surface roughnesses (Ra) of not more than 0.2 µm and flatnesses of not more than 0.2 µm; applying solution containing a bonding aid on at least one of the machined surfaces; contacting the machined surfaces with each other to produce an assembly; and subjecting the assembly to a heat treatment to produce the bonded article. The roughnesses and the flatnesses may preferably be not more than 0.1 µm. The bonding aid may preferably be a sintering aid applicable to at least one of the ceramic bodies. The ceramic bodies may preferably be one or more material selected from a group consisting of aluminum nitride and silicon nitride. The bonding aid may preferably be one or more bonding aid selected from a group consisting of a substance of yttrium and a substance of ytterbium. In the article, a layer rich in elements contained in a bonding aid is formed along the bonding interface of the article and ceramic particles are grown across the bonding interface. |
